Custom Set-Up
One of Stork EWT's strengths is in creating unique solutions to engineering challenges. Stork EWT engineers can design systems to reproduce the most extreme real world conditions. Below are two examples of Stork EWT challenges and solutions.
| Stork EWT Thermal Transient Simulation: Nuclear Qualification Testing
Challenge:
Simulate full flow (12,000 gpm) full pressure (400 psig) thermal transient where test fluid flowing through a pump would go from 40°F to 400°F within 4 seconds.
Solution:
Stork EWT engineers constructed an environmental chamber around the entire pump and preconditioned the pump at 40°F until thermal stabilization occurred. At the same time, 12,000 gallons of water were heated to a temperature of 400°F over a period of 30 hours. The pump was then energized, and flow, temperature, and pressure data were recorded at the rate of 1,000 samples per second. The pump was then run for an additional 1 hour period.

Stork EWT Impact Curvivability Simulation: Aerospace
Challenge:
Deployable Flight Data Recorder. Simulate a crash impact of 150 feet/second in a controlled, repeatable fashion.
Solution:
A steel impact paddle was constructed and attached to the end of a 30-foot centrifuge arm. The Flight Data Recorder was installed in a foam holding fixture on a hydraulic ram. The steel impact paddle was accelerated to a velocity of 150 feet/second. When stable velocity was reached, the Flight Data Recorder was then moved by means of a hydraulic ram into the path of the paddle. The photo shows the paddle on the left-hand side and the Flight Data Recorder in flight after impact. |
